Max Wind reach new heights

Max Bögl Wind AG has released the next generation of its Hybrid Tower system. The result of this is a further optimised tower design that brings new turbine generators up to the hub heights dictated by the market. Max Bogl Wind say it also makes hybrid towers more cost-effective.

The Hybrid Towers of Max Bögl Wind AG combine concrete and steel and allow hub heights of up to 190m.

The company has now developed the 2.0 version of its Hybrid Tower, which requires less material while still ensuring stability. Max Bogl Wind say the new system is more cost-effective due to changes to the foundation and interior construction and the revised segmentation and geometry of the towers.

It also claims the new foundation design simplifies pre-tensioning at the input level of the wind turbine and thus streamlines operation. Higher fatigue strengths are achieved and stress peaks in the structure are further reduced.

With the conical shape of Hybrid Towers 2.0, less tendons are necessary by optimising the load transference. The interior will now be constructed using a procedure patented by the Max Bögl Group in which the lift and ladder are mounted during concrete tower erection. Due to the parallel installation process, assembly time is reduced.

“The market demands more cost-effective wind turbines to meet the new challenges created by the Renewable Energy Sources Act (EEG 2017). Turbine technology is becoming more powerful and rotors are constantly getting bigger and heavier,”
says Josef Knitl, CEO of the Max Bögl Wind AG.

“Our Hybrid Tower 2.0 is capable of meeting both structural as well as economic requirements. This allows for the continued expansion of renewable energies under the new market conditions.”
To this end Max Bögl AG is developing customer-specific tower designs based on the hybrid tower 2.0 for the next generation of turbine generators.
